If your thermostat isn’t telling your equipment to start, it won’t switch on.
The first point is checking it’s set to “cool” and not “heat.” Otherwise your air conditioning may not turn on. Or you might have. hot air coming from vents being the heater is running instead.
If you’re using a traditional thermostat:
- Replace the batteries if the readout is clear. If the screen is displaying scrambled characters, get a new thermostat.
- Ensure the right mode is on the display. If you can’t update it, reverse it by dropping the temperature and pushing the “hold” button. This will make your AC start if the configuration is not right.
- Try setting the thermostat 5 degrees colder than the house’s temperature. Your AC won’t cool if the thermostat is set the same as the space’s temperature.
Once your thermostat is adjusted properly, you should begin getting cool air fast.
